2 <br /> Six (6) lots are proposed that average 1.47 acres in <br /> size. The remaining 6.09 acres are designated as open <br /> space. <br /> Sewage Disposal - Each of the six lots will have its <br /> own easement into the open space to serve as the <br /> nitrification field and repair area for the septic <br /> tank located on each lot. This is not a community <br /> system for sewage disposal and has been given <br /> preliminary approval by the Health Department. Under <br /> Section IV-B-10-e(h) of the Subdivision Regulations, <br /> no more than 50% of the required open space may be <br /> used for sewage treatment, utilities, or other uses <br /> which are restricted for access by the residents of <br /> the subdivision. The proposed nitrification field <br /> easements cover 38% of the open space shown on the <br /> concept plan. <br /> Access: The applicant proposes a new cul-de-sac built <br /> to NCDOT standards. A private road justification and <br /> the Staff's evaluation are included with the <br /> attachments. The existing right-of-way for Pauline <br /> Drive would be dedicated to the adjoining property <br /> owners who currently use the road. <br /> Review comments from applicable agencies are included <br /> with the attachments.

Each system for <br /> sewage disposal will be installed and inspected <br /> according to Health Department requirements. <br /> Planning Staff proposes to minimize stream <br /> crossings with a variation of the preliminary <br /> design. conditions of approval have been <br /> recommended to reduce disturbance and control <br /> erosion. <br /> The Erosion Control Supervisor has stated that an <br /> erosion control plan will be required if <br /> disturbance exceeds 20,000 square feet. The plan <br /> should include the road and driveways for lots 4, <br /> 5, and 6. He also recommended that all of the <br /> septic lines in the right-of-way and easements as <br /> well as the filter fields be installed all at once <br /> rather than as each house is built. This will avoid <br /> damage to driveways, the road, and to existing <br /> septic lines and fields. Over the long term <br /> development of the subdivision, this will also <br /> reduce the total amount of site disturbance. <br /> The Duke Forest Advisory Committee submitted <br /> recommendations regarding erosion control to help <br />
